Healthiest Cooking Oil Comparison See Charts with Smoke Points and Omega 3 Fatty Acid Ratios https://www.cancerschmancer.org/articles/healthiest-cooking-oil-comparison-chart-smoke-points-and-omega-3-fatty-acid-ratios
Chart does not take Pastured Pork Lard, Beef Tallow or Pastured Butter in consideration.
Oils on the chart are likely are CAFO-GMO!
Omega-6: Omega-3 Ratio
(plus other relevant fat information) ~

Note that almost all oils on the charts have a very high ratio of Omega 6 (INFLAMMATORY IN EXCESS) & Omega 3 lower ~ negligible!

This explains the ‘motor-like’ oil in Chips, granola & granola bars ~ Read ingredients looking to avoid Inflammatory Omega 6 oils!
FORGET THE REST TO MINIMIZE INFLAMMATION!!

From Baseline of Health
Trying to find the healthiest cooking oil can be a daunting task.  On​ one hand, you want to cook with an oil that has a high flash (smoke) point, but what is needed is to use a cooking oil that has a healthy balance of Omega 3 to Omega 6 fatty acids–and even better if the oil is Omega 3 & loaded with antioxidants and vitamins!
With CAFO-GMO (OVER PROCESSING & CREATING EXCESS OMEGA 6 ~ It becomes Inflammatory & ‘Disease~Causing’

Use EV Olive oil for Cold application or light heat!
Use Pastured Lard, Tallow or Pastured butter for frying .

Considerations:  
for high temperature cooking, select cooking oils with a high smoke point.  
For low temperature cooking, or adding to dishes and salad dressings, chose oils with a higher Omega-3 fatty acids since they promote healthy cells and decrease stroke and heart attack risk ~ They are also known for their anti-inflammatory action.  
Although you need Omega-6 fatty acids to maintain cell wall integrity and provide energy for the heart, too much Omega-6 fatty acids EXCESS can increase inflammation in the body.  
 
Knowing the smoke point of oils is important because heating oil to the point where the oil begins to smoke produces toxic fumes and harmful free radicals.

Final Recommendation For Healthiest Cooking Oils:
The bottom line is that buy and use organic, unrefined, cold-processed oils. Use extra virgin olive oil in salads or to add to cooked foods, but not for high temperature cooking.
You can use virgin coconut oil (high in beneficial saturated fats and medium chain triglycerides) for most mid-temperature cooking.
However, coconut oil has a smoke point of about 350 degrees F (171 C), which means it is not suitable for high temperature cooking.
Other choices include Pasture-raised Lard (pork), Tallow(Beef) & Pastured butter.
Use avocado oil for high temperature cooking.

Some say, Avocado oil has a very high smoke point by comparison to other cooking oils. It will not burn or smoke until it reaches 520 F (271 C), which is ideal for searing meats and frying in a Wok. Another good cooking oil is rice bran oil 495 F(257 C).  

Again, look for organic, cold-processed oil & Pastured (NonCAFO-GMO)
